III-V Photovoltaics Engineer

Mesodyne is a startup company revolutionizing power generation with its innovative Light Cell technology--using thermophotovoltaics to provide efficient, silent, reliable, long-endurance power from any fuel. By bridging the gap between batteries and internal combustion engines, Mesodyne's Light Cell technology provides more than a 10x improvement in endurance for unmanned vehicles, wearables, and various other equipment. At Mesodyne, we are committed to bringing groundbreaking products to the industrial and defense sectors, with multiple existing contracts and numerous upcoming business opportunities.

Mesodyne is seeking a highly motivated Photovoltaics Engineer. This role will be central to the development of cutting-edge low-bandgap In Ga As  PV cells and the transition of Mesodyne's innovative Light Cell technology to its first commercial product.

• Own the design, fabrication, integration, testing, and optimization of PV cells in the Light Cell.
• Develop new PV cell designs including lattice mismatched with an optimized bandgap, back contacted, multijunction, etc.
• Work towards productization by transitioning from prototype to scalable, manufacturable designs.
• Collaborate closely with cross-functional teams to build prototypes for deployment in government and commercial pilot projects.

• PhD in electrical engineering, material science, physics/applied physics, or a related field with a focus on semiconductor devices.
• A working understanding of PV cell physics and behavior. An understanding of PV cell modeling and simulation is desired but not required. Prior experience with III-V materials for thermophotovoltaics, concentrator, multijunction, space or other high performance PV devices is particularly relevant.
• Strong hands-on microfabrication experience is required, including metalization, etching, lithography and thin film deposition. Must be capable of working at local academic clean rooms.
• Hands-on PV electrical and optical characterization experience by methods such as IV, EQE, reflectance, Hall, CV, and TLM is required.
• Knowledge of III-V epitaxial growth is desirable but not required.

This position is based at our facility in Somerville, MA and will require working at local academic clean rooms.
